Agreed, I much prefer using an a frame to using a "proper" trailer, the lack of extra width is a real bonus, and the difference in weight helps too.
towing my nova with my calibra it still does 0-60 in about 10-12 seconds I reckon, its quicker than my van is driving around normally, lol
Be careful on very tight turns though, the car you are towing's steering doesnt react quick enough and it can tend to push the back of the tow car around a bit.
